So I'm guessing there is probably a setup or admin area where you inputed what you wanted for a title for the site/page/forum. Double check to make sure you don't have any unclosed quotation marks in the Title. You might even try completely removing any quotation marks or apostraphes that may be in the title (if any). Usually with Perl any string needs to be terminated with the quotation marks. If you inadvertantly have an unclosed quotation mark in your title it may be what's causing that.

Like I said, I'm not an expert with Perl...I've modified several scripts, but that would be my best guess.

I do know that they (poetic pollution) are pretty responsive, so if you haven't already done so, you might want to post your question on their support forum as well.
